Very many thanks to whoever suggested using a big blue Ikea bag as a roesack - I was facing a bill of £50 to replace my old one that has fallen apart (after 20 years mind) but the Ikea bag is sufficing nicely!
No thanks required - to clean them just stick them in the washing machine. I have friends who put me onto them - they use them ta carry all theri canoeing gear etc. But we are looking at having some made in canvas so they look a bit posher.
But then we have been talking about it for three years and can't forsee it happening any time soon.
This reminds me of the story of the man that used to leave dead rats in a box wrapped in gift paper on top of the boot of his car. I am sure that it is an "urban myth" but just don't ever go leaving that IKEA bag behind!
